ROLLS.

SPECIFICATION forming part of Letters Patent No. 659,647, dated October 16, 1900. Application filed April 12, 1899- Serial No. 712,735. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD B. CHARLTON, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Rolls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates to certain improvements in rolls for shaping connecting-plates for railway-joints, and more particularly that class of plates described in United States Patent No. 427,017, the objects of the present invention being to reduce the number of rolls required, to prevent the formation of fins caused by excessive reduction from one groove or pass to another, to secure a more perfect filling out of the fish-plate at its bearing-surfaces, and to secure other advantages and results, some of which may be hereinafter referred to in connection with the description of the Working parts.

The invention consists in the improved rolls,in their arrangements and combinations, and in the improved method of rolling fishplates, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like characters of reference indicate corresponding parts in each of the several views, Figure 1 is a sectional elevation of the roughing orpreparatory rolls. Fig. 2 is a secti onal elevation of the finishing-rolls; and Fig. 3 is a sectional View taken on line y, Fig. 2, and showing certain rings and keys or splines used in connection with the roll.

In said drawings, h, W, and 72, indicate the top, middle, and bottom rolls, respectively, of the preparatory set or train. Two sets of rolls are used in practice, as shown, the first or roughing set of rolls preparing the metal for the second or finishing set (shown in Fig. 2) and comprising top, middle, and bottom rolls, (marked f, f, and f respectively.

The top and bottom rolls of the series are each provided with annular grooves of peculiar cross-sectional shape adapted to the particular style of fish-plate or other article to be rolled, and the middle roll has male projections adapted to work in said grooves on the top and bottom rolls. Instead of having each male projection on the middle roll engage a groove on one roll and work in a va- 6o cant space or recess on the other roll, as has been usual heretofore, I have provided a construction in which each projection on the middle roll works into differently-designed grooves on the top and bottom rolls, respectively. In this way the one set of rolls presents two series of passes through which the metal may be led, and thus does the duty of two separate sets of rolls to a great economy in saving the number of rolls required. For example, in the roughing set I have the twoseries of passes shown, one marked with numerals 1 to 6, inclusive, and the alternate series marked 1 to 6, inclusive. Either of these two series is available for use, as will be understood, andinasmuch as the two series are entirely distinct and may be different the range of usefulness of the set of rolls is doubled. I furthermore have available a greater number of passes which may be employed as needed, and by increasing or diminishing the amount of reduction of metal from the preparatory to the finishing rolls the metal can be properly filled out at the bearing-surfaces of the head of the fish-plate or the formation of objectionable fins, because of excessive reduction, can be avoided-as, for example, in some designs the plate being rolled is carried from pass No. 5 in the preparatory-rolls to pass N o. 6 in the finishingrolls, and in other designs from pass No. 6 to pass No. 7 in the finishing-rolls, or from pass No. 5 to pass No. 6 In some designs the metal in process of rolling is carried through passes l to 6, or some of them, on the roughing-rolls 5 and then through passes 6 6 7, or some of them, on the finishing-rolls. In other designs the said passes 1 to 6, or some of them, are used in connection with passes 6 6 7, or some of them, on the finishing-rolls. Still, [00 again, passes 1 to 6', or some of them, on the roughing-rolls may be used with either one shown in the last passes of the finishingrolls,

or the other of the finishing series, and thus a comparatively-wide variety of designs can be produced by the one machine or mill. It will be seen that the same shapes could be rolled without placing the bottom roll at the top when it is desired to use the passes indicated by the series of primes, as I have mentioned; but said change is made because in my improved method of rolling fish-plates the plate must always be rolled with its bearingsurface downward, thereby causing the scale to free itself from the metal and producing-aclean contact-surface.

I have shown the passes on the finishingrolls, and passes No. 6 and 6 on the preparatory rolls are formed on sleeves m, m, m 1), 1), b 0, &c., which may be fitted onto the rolls when the original passes wear out by cutting down the worn pass to the same diameter as the journal, or very nearly so. The sleeves are then slipped on, beingheld against turning by keys or splines, as 70. Threaded nuts 71 are then screwed upon the roll to hold the sleeve against longitudinal displacement, said roll being threaded, as at 0, to receive said nuts. By using a right-hand screw on the middle roll and a left-hand screw on the top and bottom rolls the greater the pressure the firmer the sleeves will be held in place.

Washer-rings p may be used between the sleeves and threaded nuts, and in some cases several sleeves may make up one pass, as

where (Z d d are iron section-rings, e and e tongue-rings, and e a bending-ring. Furthermore, in my construction the tongue-rings 66 forming with the bending-rings e the final or bending pass 7, are placed within or between the housings or bearings (not shown) of the rolls the same as the other passes, and

by reason of this construction and the right and left hand threaded nuts described are held very firmly and rigidly.

Having thus described the invention, what I claim as new is 1. In a fish-plate-forming machine, a set of rolls comprising upper and lower rolls each having annular pass-grooves opposite one another, and a middle roll having annular projections forming with the said grooves in the upper and lower roll passes for the metal in rolling, the opposite members of each pair of opposite passes being of forms adapted to the rolling of diiferent fish-plates and each pass being in series with the next alternate one at the opposite side of the middle roll, whereby two independent series of alternating passes are produced which will roll distinctly diiferent completed fish-plates, substantially as set forth.

2. In a fish-plate-forming machine, a plurality of sets of rolls each set comprising upper and lower rolls having annular passves directly opposite one another, and a I middle roll having annular projections formin g with said grooves passes for the metal, the opposite grooves of the upper and lower rolls differing in cross-section and the projections of the middle roll serving in common with said differently-formed grooves to provide two differing series of passes each adapted to roll fish-plates at some stage of formation, and the sets of rolls being independent of each other, and each adapted to carry the process of rolling a fish-plate through a diiferent stage, whereby the sets cooperate to produce a complete fish-plate and either series of passes of any set can be used with any of the series of the other sets, substantially as set forth.

3. The herein-described fish-plate-forming machine, comprising a set of roughing-rolls nular pass-grooves, those on the top roll being opposite those on the bottom roll, and a middle roll having annular projections each of which enters at its opposite edges a groove in the top roll and a groove in the bottom roll, said grooves being of diiferent cross-sectional formation and producing with the common projection of the middle roll fish-platesof different construction, andthe roughing-setand finishing-set of rolls being independent of each other whereby-a series of passes of one set may be used in connection with either series of the other set, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day of April, 1899.
